Arduino Hard Drive Clock by NatureTM

“The first interrupt just records the time that the slot reaches the sensor and sets the position to zero. [It actually sets the position to the offset value since the sensor isn't at 12 o'clock and I like to think of 12 as pos 0.] Now I can tell how long a rotation takes and how long it has been since the last completed rotation.”Via hackedgadgets (read the original forum post here).
